The driver’s primary responsibility is the safe operation of the

vehicle. Driving while distracted can result in loss of vehicle control,

resulting in a collision and personal injury. FCA US LLC strongly

recommends that the driver use extreme caution when using any

device or feature that may take their attention o the road.

Use of any electrical devices, such as cellular telephones, computers,

portable radios, vehicle navigation or other devices, by the driver

while the vehicle is moving is dangerous and could lead to a serious

collision. Texting while driving is also dangerous and should never be

done while the vehicle is moving.

If you ﬁnd yourself unable to devote your full attention to vehicle

operation, pull o the road to a safe location and stop your vehicle.

Some states or provinces prohibit the use of cellular telephones or

texting while driving. It is always the driver’s responsibility to comply

with all local laws.

Driving and Alcohol

Drunken driving is one of the most frequent causes of

collisions. Your driving ability can be seriously impaired with

blood alcohol levels far below the legal minimum. If you are

drinking, don’t drive. Ride with a designated non-drinking

driver, call a cab, a friend, or use public transportation.

WARNING!

Driving after drinking can lead to a collision. Your

perceptions are less sharp, your reﬂexes are slower, and

your judgment is impaired when you have been drinking.

Never drink and then drive.

This guide has been prepared to help you get

quickly acquainted with your new Jeep



brand

vehicle and to provide a convenient reference

source for common questions. However, it is not a

substitute for your Owner’s Manual.

For complete operational instructions, maintenance

procedures and important safety messages, please

HOW TO USE THIS MANUAL

Essential Information

Each time direction instructions (left/right or

forwards/backwards) about the vehicle are

given, these must be intended as regarding

an occupant in the driver's seat. Special

cases not complying with this rule will be

properly specified in the text.

The figures in this User Guide are provided by

way of example only: this might imply that

some details of the image do not correspond

to the actual arrangement of your vehicle.

In addition, the User Guide has been con-

ceived considering vehicles with the steering

wheel on the left side; it is therefore possible

that in vehicles with the steering wheel on the

right side, the position or construction of

some controls is not exactly mirror-like with

respect to the figure.

To identify the chapter with the information

needed you can consult the index at the end

of this User Guide.

Chapters can be rapidly identified with dedi-

cated graphic tabs, at the side of each odd

page. A few pages further there is a key for

getting to know the chapter order and the

relevant symbols in the tabs. There is always

a textual indication of the current chapter at

the side of each even page.

Symbols

Some vehicle components have colored la-

bels whose symbols indicate precautions to

be observed when using this component.

Refer to “Warning Lights and Messages” in

“Getting To Know Your Instrument Panel” for

further information on the symbols used in

your vehicle.

ROLLOVER WARNING

Utility vehicles have a significantly higher

rollover rate than other types of vehicles. This

vehicle has a higher ground clearance and a

higher center of gravity than many passenger

vehicles. It is capable of performing better in

a wide variety of off-road applications. Driven

in an unsafe manner, all vehicles can go out

of control. Because of the higher center of

gravity, if this vehicle is out of control it may

roll over while some other vehicles may not.

Do not attempt sharp turns, abrupt maneu-

vers, or other unsafe driving actions that can

cause loss of vehicle control. Failure to oper-

ate this vehicle safely may result in a colli-

sion, rollover of the vehicle, and severe or

fatal injury. Drive carefully.

Failure to use the driver and passenger seat

belts provided is a major cause of severe or

fatal injury. In fact, the U.S. government notes

that the universal use of existing seat belts

could cut the highway death toll by 10,000 or

more each year and could reduce disabling

Rollover Warning Label

HOW TO USE THIS MANUAL

2

injuries by two million annually. In a rollover

crash, an unbelted person is significantly more

likely to die than a person wearing a seat belt.

Always buckle up.

WARNINGS AND CAUTIONS

While reading this User Guide you will find a

series of WARNINGS to be followed to pre-

vent incorrect use of components which

could cause accidents or injuries.

There are also CAUTIONS that must be fol-

lowed to prevent against procedures that

could result in damage to your vehicle.

engine conveniently from outside the vehicle

while still maintaining security. The system

has a range of approximately 300 ft (91 m).

NOTE:

• The vehicle must be equipped with an au-

tomatic transmission to be equipped with

SENTRY KEY

The Sentry Key Immobilizer System prevents

unauthorized vehicle operation by disabling

the engine. The system does not need to be

armed or activated. Operation is automatic,

regardless of whether the vehicle is locked or

unlocked.

The system uses key fobs that have an em-

bedded electronic chip (transponder) to pre-

vent unauthorized vehicle operation. There-

fore, only key fobs that are programmed to

the vehicle can be used to start and operate

the vehicle. The system will shut the engine

off in two seconds if someone uses an invalid

key to try to start the engine.

NOTE:

A key fob that has not been programmed is

also considered an invalid key, even if it is cut

to fit the ignition or lock cylinder for that

vehicle.

During normal operation, after placing the

ignition in the on position, the vehicle secu-

rity light will turn on for three seconds for a

bulb check. If the light remains on after the

bulb check, it indicates that there is a prob-

lem with the electronics. In addition, if the

vehicle security light begins to flash after the

bulb check, it indicates that someone used

an invalid key to try to start the engine. Either

of these conditions will result in the engine

being shut off after two seconds.

If the vehicle security light turns on during

normal vehicle operation (vehicle running for

longer than ten seconds), it indicates that

there is a fault in the electronics. Should this

occur, have the vehicle serviced as soon as

possible by an authorized dealer.

CAUTION!

The Sentry Key Immobilizer system is not

compatible with some aftermarket remote

starting systems. Use of these systems

may result in vehicle starting problems

and loss of security protection.

All of the key fobs provided with your new

vehicle have been programmed to the vehicle

electronics.

Replacement Key Fobs

NOTE:

Only key fobs that are programmed to the

vehicle electronics can be used to start and

operate the vehicle. Once a key fob is pro-

grammed to a vehicle, it cannot be pro-

grammed to any other vehicle.

CAUTION!

Always remove the Sentry Keys from the

vehicle and lock all doors when leaving the

vehicle unattended.

Duplication of key fobs may be performed at

an authorized dealer or by following the cus-

tomer key programming procedure. This pro-

cedure consists of programming a blank key

fob to the vehicle electronics. A blank key fob

is one that has never been programmed.

NOTE:

When having the Sentry Key Immobilizer Sys-

tem serviced, bring all vehicle key fobs with

you to an authorized dealer.

17

Customer Key Programming

If you have two valid key fobs, you can program

new key fobs to the Sentry Key Immobilizer

system by performing the following procedure:

1. Cut the additional key(s) to match the

ignition and lock cylinder key code.

2. Insert the first valid key into the ignition.

Place the ignition in the ON/RUN position

for at least three seconds, but no longer

than 15 seconds. Then, place the ignition

in the LOCK position and remove the first

key.

3. Insert the second valid key into the igni-

tion. Place the ignition in the ON/RUN

position within 15 seconds. After 10 sec-

onds, a chime will sound. In addition, the

Vehicle Security Light will begin to flash.

Place the ignition in the LOCK position

and remove the second key.

4. Insert a blank key into the ignition. Place

the ignition in the ON/RUN position

within 60 seconds. After 10 seconds, a

single chime will sound. In addition, the

Vehicle Security Light will stop flashing.

To indicate that programming is com-

plete, the Vehicle Security Light will turn

on again for three seconds and then turn

off.

The new key is programmed. The key fob

will also be programmed during this pro-

cedure.

Repeat this procedure to program up to eight

keys. If you do not have a programmed key fob,

contact your authorized dealer for details.

NOTE:

If a programmed key fob is lost, see your

authorized dealer to have all remaining key

fobs erased from the system's memory. This

will prevent the lost key from starting your

vehicle. The remaining key fobs must then be

reprogrammed. All vehicle key fobs must be

taken to an authorized dealer at the time of

service to be reprogrammed.
